北回蔡遠東大哥已回家靜養

像小弟跑超馬之後, 成績就不太去注意了, 因為每一場超馬都各有其相當艱難的地方, 能完跑就是大幸, 況且還有更多地方需要去留意, 不但聆聽周遭大自然的樂音, 也要倾聽自己身體的聲音, 每一動作都是順乎這些節奏.

感謝mingchu兄的專業介紹, 小弟獲益匪淺!

小弟參與的西域 100 英里耐力跑, 也有抽血檢驗, 做以下的肌肉血液分析

文章發表人 西域 100 英里耐力跑 Muscle Necrosis: It has been found that some degree of muscle cell death in the legs occurs from participation in the Run. The recovery can take several months. This seems to be a bigger problem in runners who become dehydrated or have overexerted themselves. Medical analysis of blood samples taken from Western States runners shows that this occurs to some degree in all runners.

大意是, 缺水或太操, 容易引起腿部肌肉細胞壞死.

此外, 一篇有關跑超馬的生化專論 - Biochemical Strategies for Ultrarunning http://blogs.cybersym.com/ultrarunning-biochem.html, 也提及肌肉細胞壞死,

文章發表人 Biochemical Strategies for Ultrarunning Muscle cells, like nerve cells, require appropriate amounts of potassium and sodium ions to produce action potentials, (see Appendix B: The Biochemistry of Nerve Signalling). Muscle cells also require significant quantities of calcium ions. If quantities of any of these ions get too far out of balance, the cell may generate action potentials or calcium signal spikes that have the wrong magnitude, duration, or propagation. This typically causes the cell to waste ATP in various ways. When muscle cells use up their carbohydrate reserves, their mitochondria cannot produce enough ATP, and contraction does not occur. The muscle cell is said to be fatigued. A worse situation occurs if ATP runs out during a muscle contraction or if too much calcium is released into the cytoplasm from failing mitochondria. Under these conditions the muscle cell becomes locked in a contracted state. This leads to muscle soreness and tightness. If enough muscle cells reach this state simultaneously, a muscle cramp occurs. Muscle cell carbohydrate reserves can be replenished via the bloodstream (assuming the liver has carbohydrate reserves to transfer into the blood). However, if an aerobic (high oxidative) muscle cell (Type I or Type II fatigue resistant muscle) goes too long without sufficient carbohydrate (tens of minutes), some mitochondria begin to undergo oxidative damage. Cells contain many mitochondria, but producing new mitochondria requires hours to days. If enough mitochondria are damaged, the cell itself begins to experience oxidative damage and becomes programmed for cell death. Synthesis of new muscle cells takes days.

大意是, 鈣離子失衡, 易使能量 (ATP) 過度耗費, 肌肉緊縮甚至抽筋, 若加上碳水能源補充不及, 細胞內的引擎 (粒線體), 一一逐漸壞死, 細胞過度氧化, 被迫迅速進入壞死階段, 而產生新細胞卻需要好幾天.

昨天簡姐打電話給我，

我正在開車，第一句話就說：「那個老蔡很嚴重耶！」

我第一個直覺是：「心臟的問題。」

簡姐述說症狀後，說是肌肉溶解症！

她還說不知道是不是為了拼成績？我心裡就有點內疚，破四是一種迷思？

反正多喝水，也要喝運動飲料，還好這次沒事，

我跟蔡大哥說老天爺送你一份小禮物──「身體的警訊」，

還好沒事！

他說一陣天旋地轉，心想人生就要結束了，很高興是在馬場(我聽了一陣心酸)

蔡大哥說：「我是天生的樂觀者，如果是到了人生的最後一刻，我也是大笑三聲！」

 

mingchu的資料相當重要..也希望蔡大哥順利康復...

蔡大哥在老爺馬要擴大百馬慶祝
